To all whom it may concern:

Be it known that I, Axmuiw J. BERNARD, acitizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Film- Menders; and I do hereby-declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in 'film menders, and consists more particularly in a device for mending the marginal edges of motion picture films containing the feed perforations. Incident to rough handling and usage in running films through the projecting apparatus and in rewinding thefsame for subsequent use, such films constantly sustain bre'akages, especially along the marginal edges which contain the series of perforations engaged with the drive sprockets.

It is the purpose of this invention to provide a device for securing along the broken marginal edges of films, tapes or ribbons provided with equidistantly spaced perforations'corresponding in configuration to the perforations in the edges or" the film.

Afurther object of the present invention resides in providing an improved film mender of the above character which will be equipped with a device for carrying a perforated ribbon or tape movable to a position above either of the marginal edges of the film, which is arranged upon a clamping device for holding the tape after "the same has been applied and cemented.

With these and other objects in view the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views: Figure 1 is a top plan view of an improved film Inender constructed in accordance with the present invention and illustrating a film as applied thereon. Fig. 2 is a side elevational view of the same; and. Fig. 3 is across sectional view of the improved device with parts'shown in elevation and with the ribbon attachment.

Specification of Letters Patent.

Patented Feb, '22, 191%.

Application filed June 26, 1915. Serial No. 36,498.

Referring more particularly to the drawings, wherein'one embodiment of the present invention is illustrated, 1 designates a table or other supporting structure, upon which is mounted the bed or base 2 of the improved film mender, the same being provided with lugs 3 perforated for the passage of the screws i whereby the attachment is effected.

Along the rear edge of the base 2 are hinged, as indicated at 5, afseries of clamps 6 disposed ad]acent and adapted to be independently movable about said hinge 'connections The clamps 6 are arranged to be lowered upon the base 2, in which position they secure and confine the film 7, and

where they are held by pivoted catches 8,

provided each with a cam extension 9 for riding over the free upperedge of the respective clamps and pressing the latter into close engagement with said b ase.

The base 2 is provided with separate series of teeth 10 "and 11, eouidistantly spaced and corresponding to. the sprocket holes on the filni 7. In the several clamps 6 are series of sockets 12 and 13,provided to receive the respective series of teeth 10 and 11 when said clamps are revolved to position in engagement with the base 2 to secure the film during the mending operation. The base 2 and clamps 6' areprovided with complementary channels 14: and 15, extending opposite the central portion of the film, upon which are contained the picture series whereby the parts'o'f the device will not come in contact" with said portion of the film, which would otherwise be likely to scratch or erase the pictures.

Referring now to Fig.3, the supporting structurel is shown formed with a groove 15 in which is'located bearings 16 for reequidistantly spaced perforations 21, 'corresponding 1n configuration to the sprocket holes in the film 7; By-grasping the holder 18 the rod 17 may be moved to the full or dotted line position accordingly as it is desired to bring the ribbon roll 20-above theright or left side of the film 7, in which position the ribbon can readily be drawn down and a suitable length out therefrom for mending the broken edge of the film.

The operation of mending a film may be proceeded with on the above described device in the following manner :The injured sprocket holes of the film 7 are cut off and the new ribbon or sprocket holes 20 are glued or cemented on same place as shown in Fig. l, but it is preferable to cut the old injured edges off the film as economically as possible, so as to give more place on which to glue the new ribbon 20. Practice has shown that sometimes it is even preferable just to glue a new ribbon of sprocket holes on the old ones without cutting the broken'edges off the film.

The injured film 7 is preferably cut away as indicated at 22 in Fig. 1, to remove the damaged edge of the same, and the film subsequently applied on the base 2 with the sprocket holes thereof engaging with the series of teeth 10 and 11. In this position, it will be seen that the central portion of the film' overlies the channel 14 in the base 2, and will not be scratched or injured by pressure or contact with the parts of the device. The holder 18, if the device is equipped with such, is now grasped and moved to bring the reel 20 above the cutaway portion 22 of the film 7, and the ribbon drawn down and a proper strip measured out over the length of the damaged portion. The strip is thereupon cut and applied with an adhesive to the adjacent sides of the cutaway portion 22 of the film 7, care being taken to adjust the sprocket holes 21 in the ribbon 20 to agree with the position of the perforations in said film. Such of the clamps (i as may be required, are then brought down into engagement with the film and are secured by the pivoted catches 8. After sufiicient length of time the catches 8 are removed and the clamps 6 withdrawn, when it will be found that the ribbon is permanently applied to the film 7 and forms an unbroken series of sprocket holes. The film is now in readiness for subsequent operation. I

It is obvious that those skilled in the art may vary the details of construction and arrangements of parts without departing from the spirit of my invention, and therefore I do not wish to be limited to such features except as may be required by the claims.

I claim:

1. In an improved film mender of the character described, the combination with a supporting structure, of a. base removably secured thereon and traversed by a longitudinal central channel, series of equidistantly spaced pins on both sides of said channel for receiving the perforations in the 'film margins, a series of independently hinged clamps disposed contiguous and arranged to swing down to engage the base and bind the film and ribbon together dur ing the mending operation, said clamps being provided with sockets for receiving said pins and with registering recesses adapted to aline with the channel in said base when the clamps are moved to engage the same, and catches pivoted to said base-and provided with cam heads for engaging the free ends of said clamps and binding the same in tight engagement with the base, substantially as described.

2. In a film mender, the combination of a base constructed to receive the film, means for clamping said film during the mending operation, and a ribbon holder slidably connected with said mender for bringing the ribbon over either marginal edge of said film, substantially as described.

3. A film mender including a base for receiving the film, clamp means associated with said base for securing the film during the mending operation, bearings associated with said base, a holder including a member slidable' through said bearings, said holder being adapted to support a perforated ribbon mounted on the same and movable thereby to bring the ribbon over either marginal edge of the film as the same lies on said base, substantially as described.

4. In a film mender, the combination of a base adapted to receive the film, clamp means associated with said base for binding the film during the mending operation, bearings associated with said base, a U-shaped holder having a lower horizontal member slidably mounted through said bearings and an upper horizontal member extending above the base and clamping means, said upper member adapted to support a perforated ribbon roll movable above either marginal edge of the film on said base, substantially as described.

5. In a film mender, the combination of a supporting structure having a groove therein, a base mounted on'said support? ing structure and provided with a longitudinal channel, a series of teeth on said base to either side of said channel, a series of clamps hinged to swing independently on said base and provided with channels and sockets for. receiving said teeth, means for securing said clamps in engagement with said base, a ribbon holder slidable in the groove in said supporting structure, and having a perforated ribbon roll mounted thereon and arranged to be margin, substantially as described.

In testimony whereof, I afiix my signature.
